Story summary
South Korean police raided the national headquarters of Starbucks Korea on *June 2023* (date not specified in article, but implied by mention of June events), amidst allegations of defamation surrounding a marketing campaign. The campaign, called "*Tank Day*", was launched in May, coinciding with the anniversary of the 1980 Gwangju Uprising, where hundreds were killed by military forces. The promotion featured a coffee tumbler with a tank design, which many interpreted as a reference to the vehicles used to crush protesters during the uprising. This sparked a mass boycott movement and led to a criminal complaint being filed against Starbucks Korea. Starbucks initially apologized for the campaign, stating it was unintentional, but civic groups demanded further investigation into the matter. The company's operator in Korea, Shinsegae Group, claimed that the team responsible for planning the promotion did not intentionally link the design to the historical event, and that upper management failed to notice the connection as well. As a result of the controversy, Starbucks stores across South Korea closed for half a day in *June* so staff could attend history lessons to understand the significance of the Gwangju Uprising.
